Lower Cowlitz Language (Stl'pulimuhkl)

Lower Cowlitz is a Salishan language of Washington state,
related to Chehalis. The people's original name for themselves
was Stl'pulmsh-- Cowlitz was the name of the river whose banks they lived on. The Upper Cowlitz, whose traditional homelands
are located further up the same river, are a Sahaptin tribe who spoke a dialect of the unrelated
Yakama language.
Neither Cowlitz Salish nor Cowlitz Sahaptian are spoken as first languages today, but the Cowlitz tribes are working on reviving
their traditional languages, as well as the Chinook Jargon trade
language that was used extensively in this region.
